Definitely not healthy, they should be much darker and a uniform color, even the texture of that liver is bad, it should be smooth and even not spongy at all. I can't say what exactly is wrong w/ both organs, but they are not healthy at all. It could be from any source w/ the info you have right now, no way to pinpoint cause w/o histology report. It could be congenital isolated to this bird (or genetic relatives) it could be environmental (something they are getting into that isn't killing them but is assaulting the liver) or there are some fowl diseases that attack the organs. If it were me, I would take a wait and see for right now, but if another died suddenly w/o cause I would have a professional necropsy done w/ histology report.
